Electric contact is the key components in button, and it is commonly used to join with the contact switch of printed circuit board (PCB) (pcb)
To use.It must have low contact resistance.If contact resistance is excessive, will result in key switch disabler, erroneous judgement.
The following is the example that an electric contact turns on disabler: the composite of rubber and metal lath preparation, as
During electric contact on rubber key, when being increased to 80 DEG C by room temperature, rubber occurs and swells and protrude from showing of electrical contact surfaces
As, thus affecting to turn on, make contact resistance be increased to 2 more than ω by 0.4 ω, in addition non-conductive.As shown in Figure 1.Rubber protrudes
The reason be because rubber has larger thermal coefficient of expansion.Such as, in the thermal coefficient of expansion of silicone rubber, about the 15 of metallic nickel
